Phylogenetic trees of olfactory genes (OBPs, CSPs, ORs, GRs, and IRs) from S. noctilio and S. notobei. Homologous genes of the two species cluster together. Expression levels (FPKM) of olfactory genes in male and female woodwasp antennae are displayed behind the gene names. Expression values (FPKM) are shown on a log2 scale
